This paper investigates the effect of mobile phone screen size (1.65 inches-2.75 inches) on video based learning. It first examines the educational benefits of video as a teaching medium and surveys the usage and issues related with video based learning. After which, it investigates the value of video for mobile learning. It reports on an empirical(More)
Virtual Reality is being used increasingly for upper limb rehabilitation. The type of virtual objects used for reaching tasks varies widely, but there has been little work exploring the effect of different characteristics of objects on target acquisition time. This study investigates how target acquisition times vary for virtual objects with different(More)
Music or sound effects are often used to enhance Virtual Environments, but it is not known how this audio may influence gait speed. This study investigated the influence of audio cue tempo on treadmill walking with and without visual flow. The walking speeds of 11 individuals were recorded during exposure to a range of audio cue rates. There was a(More)
(and their matched re-entries into guest-operating mode) can lead to performance degradation of 30%–50% for network intensive workloads. This observation leads directly to the au-thors' idea: Exitless Interrupts (ELI). Their solution comes in two parts. The first technique is to configure the system to deliver all interrupts directly to the virtual machine(More)
